Process Control and PLC Tutorial

Abstract: Programmable logic controllers (PLC) save time, money, and energy in process control systems. They simplify systems. A brief history of manufacturing processes sets the stage for how to use modern ICs to replace discrete components. The ICs allow easy system design and extend monitoring to improve equipment and personnel safety. The MAX15500/MAX15501, MAX5661, and MAX5134–MAX5139 serve as examples of ICs in process control.
